Which statement describes what a thermos does?
A. A thermos makes things warmer
B. A thermos stops heat transfer
C. A thermos makes things cooler
D. A thermos slows heat transfer

Answers

The best answer I suppose would be A. A thermos helps keeps things hot and doesn’t allow heat to escape. Hope this helps! :)

A thermos slows down the process of heat transfer as it minimizes the process of conduction and convection.

What is conduction?

Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,

When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:

1) heat conduction

2) electrical conduction

3)sound conduction

what could cause a population of deer to decrease?

Answers

Explanation:

more predators, less deers. also starvation, and diseases.

One thing that would cause the population of deer to decrease is the overpopulation of coyotes, bears, and wolves. Wolves and bears eat small rodents, this means that if there is a lot of rodents wolves and bears would be able to thrive therefore eating deer. Another reason deer populations would decrease is if other consumers eat producers. Deer would have a hard time keeping up as producers would not be able to grow too quickly. The last reason deer populations would decrease would be because of deforestation as humans cut down trees to make paper and other wooden utilities.

How many moles are there in 8.94*10^24 atoms P?

Answers

Answer:

14.85 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{8.94 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.850498[/tex]

We have the final answer as

14.85 moles
